Be itknown that I, AmRanMooRIIot-isr., a citizen of the United Statesof vAmerica, residing and State of Michigan, haveinvented certain new-andV useful Improvements in Dust-"- Caps for Automobile Starting-Crank Shafts, of which the-following is a speciticatiomref A erence.beinghad therein to the accompanying drawings.-

Ihe invention relates tolautomobile start' ing .crank constructions,- andjit is'the object.

i-of the invention to provide a dust cap or inclosing casing for the mechanism when the crank is removed.

It is a 'further objectto utilize the spring which normally 'reftracts thestarting. crank from its enga ement with the engine crank A is the'starting' crank shaft', which is journaled in a suitable bearingf-B attached 4to 'the cross .bar C-or other supporton the;v

vehicle `frame. The inner end of thiscrank shaft is suitably fashioned'at D for engagement with the engine crankA shaft, the posi-"1 tion of the I atterbeing indicated byrdottel lines at E.

F is a spring for normallylholding the shaftA out of engagement ngi-th the crank shaft E, one end ofsaid.=spr ing abutting against the shoulder G on vthe bearing B,l while the opposite end engages a collar H- on the. shaft A. This collarA is notched at,

I for interlocking with the (not shown).

When the crank is I not in use it isremoved from the crank shaft A,v and to protectthe parts from dust they are inclosed by a cap starting crank or tubular casing J and this cap fits over a tubularextension K of the'bearin'gB, to

which' it Vis preferably secured by a .bayonet lock, comprising the slot L in the cap and the pin lMon the member K.. The cap J is y so proportioned thatduring the engage-.-

ment of the pin M with the bayonet slot .L

the'end ofthe cap will press against the end of the stai-ting crank shaft A, and move the latter forward against the tension of the spring'F bearingupon the collar H. Thus "7 l' specication of Letters Patent.

What I claim as'my invention is:

1. The. combination with a revoluble and longitudinally adjustable shaft,- of a ,bearing Vin which said shaft is mounted and from which va portion of the shaft projects, resilient means for yieldably resisting forward movement of said shaft 1n its bearing, anda ca for housing the projecting .portion of gagement. with said bearing andheld in such engagement by said resilient niember.

shaft -j'ournaled and longitudinally adjust .able in-said bearing, having an outwardly enga'glng said bearing, and a spring vfor yieldably projecting said shaft, adapted to said cap.

The combination with a bearing 0f"a shaft journaled and longitudinally adjust-F able in said. bearing, having anbutwardly projecting portion, acollar on'said projecting port-ion of the shaft, a spring sleeved on said 'shaft between said collar and said bearing, a tubular cap for. housing' the projecting end of said shaft, the collar'a'nd the vspring sleeved thereon, the end of said cap bearing against said shaft and telescopically ing means for said cap with said bearing,
